Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed February 25, 1907. Serial No. 359,102.

To all whom it may concern:

Be it known that I, GEORGE G'. SCHROEDER, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Denatured Alcohol Coole Stove Burners, of which the following is a specification.

This invention has relation to burners for cook stoves adapted to use denatured alcohol as a fuel and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to provide a burner of the character indicated which is adapted to convert liquid fuel into a gas and burn the same about the oven of a cook stove.

The device consists primarily of a gasifying chamber which is located in the re box of the stove and which is connected by a pipe with an elevated fuel supply tank. Burners are located upon the said chamber and branch pipes lead laterally from the said chamber, and burners are attached to the said branch pipes. The last mentioned burners are located over the oven of the stove. Each of the said burners is provided with a valve by means of which the supply of gas from the gasifying chamber to the burners may be regulated. Each burner is also provided with an air mixing chamber and suitable admission air ports. The said gasifying chamber is preferably parallelepiped in configuration, and consequently presents much heating surface to the liquid fuel as the same is introduced into the chamber and whereby the process of gasifi-` cation is facilitated. A starting pan is located under the said gasifying chamber and a pipe leading from the main fuel supply pipe terminates over the said starting pan and is adapted to deliver liquid fuel into the same for the purpose of initially heating the parts when the said fuel is ignited in the pan.

In the accompanying drawings Figure l, is a side elevation of a cook stove with parts broken away showing the burner located therein. Fig. 2, is a top plan view of the stove with parts broken away and showing the burner located therein. Fig. 3, is a perspective view of the burner detached from the stove. Fig. Li, is a vertical sectional view of the burner, and Fig. 5, is a transverse sectional view of the burner.

The burner comprises the parallelepiped gasifying chamber l, hollow in its interior and to which is connected the fuel supply pipe 2. The other end of the said pipe 2, is connected to the elevated fuel supply tank 3. The chamber l, is located in the firebox 4, of the stove 5. The starting pan 6, is located directly below the chamber l, and is spaced from the same.

The said pan is of the same horizontal area as the burner and the edges of the two said parts are vertically flush. The cross bars 7, 7 support the pan 6, and the legs S, 8, support the chamber l, above the said pan.

The pipes 9, 9, are erected from the upper side of the chamber l, and cach pipe is provided with a valve l0, the stems of which project through the sides of the fire box fi. The branch pipes 1l, 1l, extend from the side of the chamber l, and are also each provided with a valve as at l2. Each of the pipes 9, and ll, are provided with a mixer and burner 13. As these burners are of the same construction, a description of one will answer for all,

The burner consists of a flat perforated top plate 14, and the under concaved plate 15. The said plates are connected together at their edges, and the lower plate l5, is concentrically mounted upon its supporting pipe. The plate l5, is provided with the lower air admission ports IG, and the peripheral mixture outlet openings I7.

The reduced pipe 19 is connected at one end with the supply pipe 2, and at its other end projects between the chamber l, and'the pan 6, and terminates above the latter. Said pipe I9 is provided with a valve 20. The pipe 2, is provided with a section 22, which is located between the chamber l and the burners mounted upon the pipes 9, 9, and extends parallel with the said chamber. The branch pipes ll, extend laterally over the top of the oven 23 of the stove 5.

From the foregoing description it is obvious that the liquid fuel may be led from the tank 3, through the pipe 2, and pipe I9 (after the valve 20, has been opened) into the starting pan G. This fuel is then ignited and the resultant flame completely envelops the chamber l, and the pipe 2. Thus the metal is heated and the fuel contained in these parts is gasified. The valves 10, and l2, are then opened and the gas passes through the pipes 9 and Il, to the burners 13, where it is mixed with air and the resultant mixture escapes through the openings 17, and is ignited. The section 22, of the pipe 2, by reason of its close proximity to the burners mounted upon the pipes 9, will continue to vaporize the liquid fuel passing therethrough on its way to the chamber l. Also by reason of the arrangement of the burners the fire may be confined to the lire box of the stove or the fire box and the spaceover the oven or in the space over the oven as occasion or necessity may require.

Thus it will be seen that a simple and effective heater for a cook stove is provided, and that the same may be operated in great variety of ways and to advantage with the greatest degree of safety. The burner is unattended by smoke or noxious gases, and is admirably adapted for domestic purposes in the capacity hereinbeiore set forth.

Having described my invention, what I claim as new and desire to secure by Letters Patent s:-

1. A burner of the character described comprising a parallelepiped gasifying chamber, a plurality of burners arranged along the top thereof and communicating with the interior of the chamber, a feed pipe extending longitudinally of the chamber and interposed between the latter and said burners, said pipe leading into one end of said chamber, and branch pipes leading from one side o1 said chamber and each provided with a burner.

2. A burner of the character described comprising a parallelepiped gasit'ying chamber, a plurality of burners arranged along the top of said chamber and communicating with the interior thereof, a feed pipe extending longitudinally of the chamber and interposed between the latter and said burners, said pipe leading into one end of said chamber', branch pipes leading from one side of said cl1amber and each provided with a burner, a starting pan located beneath said gasifying chamber, said starting pan being of the same dimensions, in plan, as said chamber, and a supply pipe leading from said feed pipe to said pan.

3A A burner of the character described comprising a parallelepiped gasifying chamber, a plurality of burners arranged along the top of said chamber and communicating with the interior thereof, each burner being formed 0f a eoncaved plate provided with lower air inlets and peripheral flame outlets, and a Iiat perforated plate resting on the edges of said concaved plate, a feed pipe extending longitudinally of said chamber and interposed between the latter and said burners, said pipe leading into one end of said chamber, and branch pipes leading from one side of said chamber and each provided with a burner.

L A burner of the character described comprising a starting pan having laterally extendcd'b'ars adapted to support the same, a parallelepiped g'asii'ying chamber having supportingl legs resting in said pan, a fuel supply pipe leading to said chamber, and a plurality of burners communicating with said chamber.

5. A burner of the character described comprisinga starting pan having-laterally extended bars adapted to support a parallelepiped gasifying chamber having supporting legs resting in said pan, a fuel supply pipe leading to said chamber, burners arranged upon said chamber, branch pipes leading from said chamber', and burners on said branch pipes.

In testimony whereof I ailix my signature,V in presence of two witnesses.
